Sampling Location by John Van Hoesen from the GigaPan IODP 145 881A 1H 01 by John Van Hoesen

This is an example of the type of indentation made in the core when taking a sample with a toothpick. The sample is then smeared onto a glass slide to make a smear slide for inspection under a microscope.

Smearing by John Van Hoesen from the GigaPan IODP 145 881A 1H 01 by John Van Hoesen

This is an example of smearing that occurs when the core is cut in half using a thin wire. As the core is pressed down against the wire, sediment is sometimes dragged with the wire.
